more wire for WS2310 windsensor

Hi from France…
I’ve a Lacrosse WS2310 weather station, and I would like to setup my wind sensor a lttle more far from the house (because of wrong datas, the wind speed measured is too low anf far from the reality…!).

Can I put some RJ45 Cat 5 wire to make the longest wire possible between the wireless sensor and the wind sensor (I think it’s possible to have 20 meters wire maximum, as La Crosse says…)

Thanks in advance for the answers…
